My eyesight is not all that good—I’ve worn glasses since I was in fifth form. I actually use two different glasses (both bifocals). One is for general use: the top portion is for distance use—driving, watching movies, recognizing people, etc. and the bottom part is for reading.
My second pair I use in the office and when online: the top part of my glasses is for computer use (really the middle part of a tri-focal prescription) and the bottom half is for reading.
I'm nearsighted. Without my glasses I couldn't even read the computer screen and I have to put a book close to my face. My glasses are pretty much as thick as glass Coke bottles now.
Well lets just say without my glasses I can't see the bus until it hits me.
But mercifully I can read a book without glasses, and I love reading!
I can walk about the house without glasses no problem, it just hurts when I crash into things, and I sometimes walk into the cupboard thinking its the toilet [damn its dark in here].
